IS420ESWBH3A   太网IONet交换机  具有8个端口

IS420ESWBH3A是一款以太网IONet交换机，是GE Speedtronic Mark Vle燃气轮机控制系统的一部分。它有8个端口.10/100BASE-TX。ESWB以太网10/100交换机专为满足实时工业控制解决方案的需求而设计，是Mark Vle和VIeS安全控制系统中使用的所有IONet 交换机所必需的。它是一个DIN导轨安装模块。为了满足速度和功能的要求，提供了以下功能。

- 802.3、802.3U、802.x、兼容性

- 10/100基铜，具有自动协商功能。全/半双工自动协商

- 100 mbps FX-上行链路端口.HP-MDIX自动感应

-LED指示链路存在、活动、双工和速度端口的状态(每个LED有两种颜色). LED指示电源状态

·最小256kb缓冲区，具有4k媒体访问控制(MAC)地址。冗余电源输入

IS420ESWBHBA安装

对于新安装，使用DIN导轨将交换机安装在控制系统面板上。根据系统的冗余和要求连接铜线线和或光纤线。将交换机连接到配电板的28V直流电源。

IS420ESWBHSA配置

IS420ESWBH3A开关外壳可以采用DIN导轨安装或面板安装(开关通过支架安装到面板后壁)。DIN导轨安装系统符合振动和冲击要求。两种安装类型都可以轻松访问用户连接。

工业以太网交换机IS420ESWBH3A是通用电气设计的Mark Vle安全控制系统的一部分。该交换机没有任何光纤端口，但有10个铜端口，铜端口是100/45Base-TX RJ<>端口。交换机的主要操作是作为—级以太网交换机执行，其核心是缓冲组播和广播数据包的能力。应该有足够的空间来允许每个端口缓冲一个数据包;如果多个传入流被发送到交换机，它只能接受多个流中的一个传入流，并将缓冲剩余的流以供以后传输。

IS420ESWBH3A开关上有LED指示灯。有一个电源LED，其余 LED是活动和链接功能。当链路LED呈黄色常亮时，表示正在使用10 MB链路，当绿色常亮时表示正在使用100 MB链路，无LED灯表示没有链路。活动LED的颜色也是绿色和黄色，但它们会闪烁，当LED闪烁绿色时，表示活动处于全双工状态，当闪烁黄色时，活动处于半双工状态。

The IS420ESWBH3A is an Ethernet IONet switch that is part of the GE Speedtronic Mark Vle gas turbine control system. It has 8 ports.10/100BASE-TX. The ESWB Ethernet 10/100 switch is designed to meet the needs of real-time industrial control solutions and is required for all IONet switches used in the Mark Vle and VIeS security control systems. It is a DIN rail mounting module. In order to meet the requirements of speed and functionality, the following functions are provided.

- 802.3, 802.3U, 802.x, compatibility

- 10/100 base copper, with automatic negotiation function. Full/half duplex automatic negotiation

- 100 mbps FX- Uplink port. HP-MDIX automatic sensing

-LED indicates the status of link presence, activity, duplex, and speed ports (each LED has two colors). LED indicates the power status

· Minimum 256kb buffer with 4k Media Access Control (MAC) address. Redundant power input

The IS420ESWBHBA is installed

For new installations, the switch is mounted on the control system panel using DIN rails. Connect copper and/or optical cables according to the redundancy and requirements of the system. Connect the switch to the 28V DC power supply of the switchboard.

IS420ESWBHSA configuration

The IS420ESWBH3A switch housing can be DIN rail mounted or panel mounted (the switch is mounted to the rear wall of the panel via a bracket). DIN rail mounting systems meet vibration and shock requirements. Both installation types provide easy access to user connections.

The industrial Ethernet switch IS420ESWBH3A is part of the Mark Vle security control system designed by General Electric. The switch does not have any fiber ports, but has 10 copper ports, which are 100/45Base-TX RJ<> ports. The primary operation of the switch is to perform as a Level-one Ethernet switch, the core of which is the ability to buffer multicast and broadcast packets. There should be enough space to allow one packet buffering per port; If multiple incoming streams are sent to the switch, it can only accept one of the multiple incoming streams and will buffer the remaining streams for later transmission.

The IS420ESWBH3A switch has an LED indicator. There is a power LED and the rest of the leds are active and link functions. When the link LED is steady yellow, it means that the 10 MB link is in use, when the green is steady on, it means that the 100 MB link is in use, and no LED light means that there is no link. The color of the active LED is also green and yellow, but they will flash, when the LED flashes green, it means that the activity is in a full duplex state, and when it flashes yellow, the activity is in a half duplex state.
